@NicoK ï¼thank you for explanation, and I already trace the code in your
local branch. Wish your further change commit in global pool.
@StephanEwen , thanks for further elaboration. From my understanding, each
task can decide the core number of buffers in `LocalBufferPool` based on input,
output channels and configuration, the maximum number of buffers based on
`ResultPartitionType`. And all the `LocalBufferPool`s make effect on the total
number of buffers in `NetworkBufferPool`, may need consider maximum memory
usages.
And my concern is to consider the memory usages in `NetworkBufferPool`
before starts the `TaskManager`, and this part of memory should be added into
the total resource of `TaskManager`.
I am willing to do that as a part of my current work in [Fine-grained
Resource Configuration](https://issues.apache.org/jira/browse/FLINK-5131) after
this feature completes.
